Low Frequency Standing Waves in Cylindrical Structures [closed]
What would be the frequency of the fundamental vibration in a 50 meter tall cylindrical structure if it were closed at the bottom?
L = wavelength/4 for closed end cylinders so the wavelength I ...

Sum and Difference Frequencies - Amplitude Modulation
I understand that while transmitting an envelope through a carrier wave to the receiver, an upper sideband and a lower sideband form adjacent to the carrier wave. The sidebands are apparently an ...

Frequency of the sound when blowing in a bottle
I'm sure you have tried sometime to make a sound by blowing in an empty bottle. Of course, the tone/frequency of the sound modifies if the bottle changes its shape, volume, etc.
I am interested in ...

How to reconstruct information from a graph of an oscillation? [closed]
We are given a graph of the position of a wave (amplitude).
How can we calculate the wavelength, frequency and the maximum speed of a particle attached to that wave?
We have
Speed = wave length ...

How do you super impose two or more signals to occupy a fix area of space with the resultant summed wave?
Is it possible to super-impose two or more signals all sent from different directions as a standing wave with the resulting summed wave occupying a fix area of space that is also a complex area?
Do ...

Can the equation $v=\lambda f$ be made true even for non sinusoidal waves?
The known relation between the speed of a propagating wave, the wave length of the wave, and its frequency is
$$v=\lambda f$$
which is always true for any periodic sinusoidal waves.
Now consider:
...

Why does wavelength change as light enters a different medium?
When light waves enter a medium of higher refractive index than the previous, why is it that:
Its wavelength decreases?
The frequency of it has to stay the same?

What determines color — wavelength or frequency?
What determines the color of light -- is it the wavelength of the light or the frequency?
(i.e. If you put light through a medium other than air, in order to keep its color the same, which one would ...

Will a photon emitted from something moving quickly have a shorter wavelength?
If a photon is emitted from a light source moving at any speed, the photon will nonetheless always move at c (assuming it is emitted in a vacuum.)
If the speed of a photon's emitter cannot influence ...
